It is my understanding that rifling a spherical bullet IS effective. The spin axis parallel to the direction of flight helps maintain a straighter (more accurate) path because the projectile has ROTATIONAL INERTIA. Because of this resistance to a change in rotational motion, the bullet will spin about the axis and the axis will not change direction, keeping the path straighter.
Of course, you are right in that the distances and speeds we are talking about, rifling spin will have very, very little effect on the path of the ball compared to the inital launch velocity.
